Huge cleanup for games

Recently, Sascha Wildner committed a huge number of changes to the various games, bringing them in line with what’s on NetBSD and style(9). This was all put together by Ulrich Spoerlein.

I draw attention to this not because it changed anything with the games in a functional sense, but because it’s huge (450 files changed, 31450 insertions(+), 29998 deletions(-)) and because it came out of nowhere. It’s always nice to have new surprise contributions arrive.
